CHICAGO, Sept. 9, 2011 /PRNewswire/ -- Four free stock picks are being made available today on Zacks.com. The industry's leading independent research firm highlights one Zacks #1 Rank Strong Buy or a Zacks #2 Rank Buy stock for each of the four main styles of investing: Aggressive Growth, Growth & Income, Momentum, and Value.

From 1988 through the present – a period that included serious corrections and recessions – the Zacks #1 Rank Stocks have nearly tripled the market with a fully documented average gain of +28% per year.

Here is a summary of today's selected stocks that are now highly rated by Zacks:

Under Armour, Inc. has seen big gains over the last two weeks after rebounding sharply from a key, long-term trend line. That movement has been driven by strong fundamentals, with an average earnings surprise of 22% over the last four quarters and bullish growth projection supporting momentum for this Zacks #1 Rank stock.

How hot has the art world been? Sotheby's Inc. just had the best quarter in the company's 267-year history. This Zacks #2 Rank (buy) has the powerful combination of both growth and value as it trades with a PEG ratio of just 0.6.

Underlying the four free stock picks is a simple truth that first appeared in a Financial Analysts Journal article published in 1979. Leonard Zacks, a Ph.D. from M.I.T. found that "earnings estimate revisions are the most powerful force impacting stock prices." Zacks #1 Rank is awarded to a stock when analysts sharply upgrade their estimates of what the company will earn.
